You're not going to find anymore gun-related deals on Groupon, at least temporarily. The company says the entire fire arms category is under review:

All scheduled and current gun-related deals featured on Groupon North America, including shooting ranges, conceal-and-carry and clay shooting, have been placed on hiatus while we review internal standards that shape the deal inventory we feature. The category is under review following recent consumer and merchant feedback.

The news came after Michael Cargill, owner of a gun shop in (where else?) Texas, said a Groupon for concealed handgun training at his store was cancelled before it was set to expire. Cargill says he was told by company reps that the decision to kill gun deals came directly from CEO Andrew Mason. Mason might have a reputation for being kind of a nut, but you have to hand it to him—this is a good decision. And though Groupon hasn't gone into detail on the reasoning behind it, you simply have to open Facebook for two seconds to understand that guns are very sensitive subject right now.
